The intent of this document is
to offer guidelines for those interested in protecting their property from lake
erosion. This is not an all inclusive document with regard to
engineering, design, construction, or the like, and is not to be relied upon as
a substitute for hiring a contractor or other competent professional.

The CWLHOAand community are very concerned
about the expense being incurred dredging the lakes.Because of this process, our community funds are being tied up
for maintenance instead of being used to enhance our community.

Owners of lake front property have additional expenses and
responsibilities that are incurred.One
of these responsibilities is protecting your property from erosion.

Your community Lake Committee members have compiled some
information to guide homeowners when installing retaining walls.We hope that you will find the information
useful.

EDUCATION

Constant
water movement causes erosion.The lapping of the water on your property slowly eats away at the
waterline.Over time there is a
gap between the lake bed and your yard.Generally, when we get one of our torrential downpours big chunks
of unprotected
yard break away and fall into the lake bed.

Lack
of proper foundation and backfill for existing walls is a major culprit
of erosion.If a wall was initially built incorrectly the same
scenario occurs only it takes longer.The ground will
sink behind the
wall.Dirt can be added to the top but that is just providing
more fill for the lake.Over time
this gives the impression that the lake is not as full as it used to be. The
erosion in the lake may
be one reason it appears that our
lakes are not maintaining the water level they used to.The only other explanation for this
would be that every spillway has lowered.Because this seems to be happening on lakes A, B and C it seems
unlikely that both spillways are sinking at the same time

GUIDELINES

Have
plat available or a
survey
of your property.Most lake front homeowners actually own property into the
lake.Whether this was deeded at
the time of purchase or because of property erosion it is yours to
maintain.

Choose
a material that is TDEC approved.Concrete, rip rap, Versa-Lok blocks to mention a few.Because of environmental issues treated
lumber and railroad ties are unacceptable materials for the lake.

Once
material is chosen and you have determined your property line, don’t forget to submit
a plan to the property manager.The plan will be submitted to the CWL board for approval.Do not start any work until the project
has been approved.

Walls constructed
without board approval shall be subject to corrective action according to CWLHOA
Rules and Regulations.

SPECIFICATIONS

The
base of the wall has to be below the water line.A trench will have to be dug to
accommodate a minimum of 6” into solid lake bed by 24” wide for the
base.The base should consist of
COMPACTED gravel or crushed stone.The first layer of wall material should be below water level.If a system other than rip rap is used the 1st layer should be anchored
with rebar.

Once
the 1st layer of wall material is installed cover with fabric.This will keep the lapping water from
reaching the base of the wall and damaging its’ integrity.This is very important because our
water level drops during drought season.

Backfill
material for the next
layer must consist of COMPACT native soil.

Once the wall has
reached above water level the next 13” of backfill will consist
of COMPACTED drainage aggregate.This should be a minimum of 1’ wide.

a.Pour 3” of pea gravel

b.Compact

c.Lay a drainage pipe.3-4” perforated pipe should work

d.Add 10” of pea gravel on top of that.Compacting as you go

e.If your wall is more than 4’ tallit is recommended that you use fabric every 1’ as a soil
reinforcement

f.Remaining backfill will be COMPACT native soil topped off with
sod.
